Volcanoes

Problem Scenario

The reason I chose this project is because this could help science test figure out how mountains and volcanoes are formed.

Broad Question

what shapes a volcano

Specific Question

does partickle size alter the steepness of the volcanoe

Hypothesis

Ithink that the particle size will judge the steepness of a volcnoe

Graph of Hypothesis

Variables

Independent Variable: Particle size

Dependent Variable: Steepness

Variables That Need To Be Controlled:time and air preacher

Results

my graph shows that because pure sand does not contain any type of small rock that it is able to make the sand volcano steeper. unlike sand like middle grained sand doesn't work as well because it's bigger it can be jammed or it won't come out as fluent.

Conclusion i except my hypothesis because like i thought do by particle size it will judge the steepness of a volcano.

Abstract

During this experiment i wanted to see if things like particle size judge how steep
